The analysis of periodicity of polarizability and polarizing radius of atoms is executed depending on a atomic number in D.I.Mendeleyev's table. It considered energy of binding of multielectronic atoms with polarizing radius. The substantiation is given to an empirical equation.

The comparative analysis of concepts of atoms radiuses from number of the most used in different sections of physics is given. To their number concern van-der-Waals, kinetic, orbital, covalent and etc. radiuses. The substantiation of necessity of introduction in use of "polarizing" radius as self-congruent structural parameter of atom is given. Fundamental bond of polarizing radius of atom with his polarizability is shown.
[The fact of presence of the clear borders of the atom, shown in this paper is a proof of nonaplicability of Shroedinger's model of the electron as a "cloud of probability" for atom shells. - K.Kh. ]

The new approach to the description of the deformational
polarization, based on model of elastic deformation of electronic environments of atoms and molecules is offered. The given approach essentially differs from the dielectric description accepted now, based on model of lorents spheres of medium continuous. The material equations of polarization for different classes of substances, including molecular,
covalent, ionic and proton which theories as parameter contain energy and-or coordination number are received.

Published in 2004 by the Siberian Publishing House "SCIENCE" 510 pages folio of professor Alexey POTAPOV "DEFORMATIONAL POLARIZATION - the search of optimal models" at once after issuing became a bibliographic rarity. Its circulation is only 300 copies!
Strictly classical and at the same time revolutionary work of professor Potapov uncovers the unique capabilities of optical methods in deep study of the material properties. As against of destructive study using particle accelerators, optical study, based on straining-polarizational properties of material allows comprehensively and multiply (in dynamics) investigate the matter, discovering very thin, deep and composite properties.
In this unique monography the research background in the area of deformational polarization are considered. The new approach to the description of deformational polarization based on the model of elastic deformations is considered. That model bases on features of the electronic shells of atoms and moleculas changing under operation of electrical field. The equations of deformational polarization for different classes of materials are obtained. The analysis of their conformity to experimental data is made. There are hundreds of very useful for the researchers formulas, physicochemical properties, extremely necessary for materials and their molecular structure study.
